* elf64-sparc.c (struct sparc64_elf_link_hash_table): New 'sgot' and
'srelgot' fields. (create_got_section): New function. (sparc64_elf_create_dynamic_sections): Likewise. (sparc64_elf_check_relocs): Invoke create_got_section instead of _bfd_elf_create_got_section. Use the sgot and srelgot shortcuts. (sparc64_elf_size_dynamic_sections): Use the srelgot shortcut. (sparc64_elf_relocate_section): Use the sgot and srelgot shortcuts. (sparc64_elf_finish_dynamic_symbol): Likewise. (sparc64_elf_finish_dynamic_sections): Use the sgot shortcut. (elf_backend_create_dynamic_sections): Define to sparc64_elf_create_dynamic_sections.
